The twin-shaft dust humidifier, also known as the twin-shaft dust humidifying mixer, uses two sets of spiral blades for mixing, featuring high mixing efficiency, minimal floor space, and spiral blades made of wear-resistant special alloy or composite ceramic for long service life. The twin-shaft dust humidifying mixer (dust humidifier) employs a cycloidal pinwheel reducer for transmission, ensuring smooth operation and low noise. The twin-shaft mixer feeds from the top and discharges from the bottom, with a rational structure. The twin-shaft dust humidifying mixer (dust humidifier) has tight seals between mating surfaces for smooth operation. It is equipped with a humidification spray system that sprays water evenly, adjusting the water supply to meet requirements. The twin-shaft dust humidifying mixer (dust humidifier) uses a hand-pumped oil pump to centrally supply lubricating oil to the four transmission bearings, making the equipment easy to use and maintain. The twin-shaft dust humidifying mixer (dust humidifier) is a device for spraying water, mixing, and blending powdered materials.
